"I recently had an energy audit and insulation work done by Avid Energy, and honestly, the whole experience was great. The team was friendly, knowledgeable, and really easy to work with from beginning to end. They took the time to walk me through the audit results, suggested practical improvements, and got the insulation work done quickly and without any mess. It’s only been a short time, but the last couple hot days my house has stayed cool when in the past the ac used to be running all the time…the insulation definitely made a difference."

"I whole heartedly recommend Airco. Their team was experienced, skillful, friendly and professional throughout the duration of this job, from Joe's first visit to my home to discuss air conditioning options to Derek and Cam's final touches on the duct system. I had complete confidence in them, as well as in Steve, Danny, Frank and Patrick. Additionally, Airco's connections to MassSave and Commerce Bank meant financing and payment options to suit my budget. No more hauling loud and heavy window a.c. units up from the basement. Instead, I am enjoying consistent cooling throughout my home with no noise whatsoever. I am a very happy customer!"

Energy Efficiency Auditing FAQs, answered by experts

Typically, triple-pane windows made with krypton gas filling are the most energy efficient. A window’s frame, glass, design, and installation all affect its energy efficiency. These windows, in particular, are designed highly effectively in terms of their ability to insulate.

Yes, skylights can affect a home’s energy efficiency, either positively or negatively. Properly installed, energy-efficient skylights with Low-E coatings, double glazing, and UV-blocking glass can help regulate indoor temperatures and reduce heating and cooling costs. However, poorly insulated or older skylights can contribute to heat loss in winter and excess heat gain in summer, lowering overall energy efficiency.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

To find a reputable home energy auditor, start by researching local companies that offer the service and check their reviews, methods, and certifications. The most reputable professionals are often Home Energy Professional (HEP)-certified by the Building Performance Institute (BPI). You can also consult the Department of Energy’s certified list of energy auditors or use a state licensing tool to review local guidelines and ensure you are hiring a certified professional for your area.
